SOURCE: Toshiba 50H81 TAC0151 Blowing Fuses, I Need schematic

Well without the schematic, knowing Toshiba they have alot of convergence problems, so see if the fuse blown in the convergence area, if you you may have to replace convergence amps. These are the big STK's. Most of the time there was a color problem with set before going out. If no problem with this on your set then look in the HV area Hor. and Ver. area. Hope this helps!

SOURCE: dash lights dont work

sounds like you probably just blew a fuse , check your fuses , there should be a diagram on the fuse pannel cover that tells you what each fuse is for.

SOURCE: Headlights cut out after being on 10 to 15 minutes

I had the same exact problem. I found that I could make the lights come on by pushing on the top connector on the front side of the lighting control module (LCM). I pulled the connector off, cleaned it and put it back together with some dielectric grease. Only time will tell if I fixed it. On my car, it would only have problems after the headlights had been on for about 3 hours; kind of hard to re-create.

SOURCE: need Wiring Schematic/Diagram for 89 Astro GT16 boat

In all honesty, its probably impossible to get the original wiring diagram. Also, I would be willing to bet that there has been alot of re-wiring and changes made to the wiring and electrical system of the boat. If you describe exactly what your trying to do, install fix or re-wire I may be able to better assist

I bought your fog machine ,there was no remote control in the box,how do I get one


what brand and model did you buy...Some come with a remote...some are DMX and are meant to be controlled by a light system board or controller or some type. These typically dont come with a remote....You can always buy a controller or a wireless dmx remote as well.

My running lights are working just fine no brake lights any suggestions? 1999 Lincoln continental


Brake light switch ? Lighting control module , fuse's ?
The stoplight switch is protected by Fuse 32 (15A). This fuse is hot at all times. With the stoplight switch closed, power is provided to the stoplamps through the lighting control module through Circuits 9 (LG/O) and 5 (O/LB). Ground is provided to the stoplamps through Circuit 57 (BK).
Symptom Chart-Stoplamps
Refer to the Electrical and Vacuum Troubleshooting Manual for connector numbers cited in the pinpoint tests. Use Rotunda 88 Digital Multimeter 105-R0053 or equivalent to perform pinpoint tests.

Chauvet Obey 70 service manual


They are not worth trying to fix, if you really like this unit you can get a secondhand one for about 25GBP or find one from a decent manufacturer or even better how about a USB interface to DMX for your PC?

How do i connect lights to a yamaha emx 512


There is no way to hook up any form of lights to the Yamaha EMX512S. If you want to use DMX lights, you would need to buy a DMX controller. There are both analog and software controllers. Controller prices can range from $50 to over $500.

I have an Elation FC400 DMX foot controller and an Eliminator ED15 Dimmer pack (8 plug ins). Cannot get controller to do anything when Dimmer Pack set to Slave mode, Dimmer pack works fine on Programs...


In slave mode the second pack should be controlled by the first pack in the chain, not the foot controller. I think you probably don't want to be using slave mode if you are using external controller... try setting the packs to the same address so they both track the foot controller.

D4dmx-md5 stop working. No schematic. Problem came slowly then it stop working. Get a bit of light on the led display Maybe a power supply problem


You did not post enough information on symptoms to get a good answer. However, the most common problem with these dimmer packs is a failure of the sermiconductor that controls the amount of power going out to the attached light. In the D4DMX, there are 4 such, of a type class of semiconductors known as "triac", part industry part BT16A (the "A" is important, as it indicates an internally insulated mounting/heatsink tab). When this part fails, the output channel stops working, but the other 3 channels continue to work. Altho rarer, it is possible for multiple channel triacs to fail. The failure of a triac is typically due to (1) attached bulb filament failure (in a manner where a filament fragment shorts across the mounting posts), (2) channel overload (eg, plugging in a greater load (significantly greater wattage) than the D4DMX channel is rated for), (3) AC power line surge. You need to be a trained & experienced ELECTRONICS (ie, NOT electrician) to accomplish this repair safely & satisfactorily, and it involves soldering & specialized test equipment.
The D4DMX series is also known for failures of its control cable interface circuitry, both for Microplex and DMX. Microplex failures is more common, as that type of interface is more sensitive to induced noise from nearby AC wiring, radio signals, and standing wave reflections from varying lengths of control cabling. DMX uses a differential control signal interface, which makes it much more immune to induced noise, but it operates at a lower signal voltage which makes it more sensitive to accidental application of improper voltages on the control cable...which often happens when someone connects the DMX ports on the dimmer pack to a Microplex connector on another pack or the control console. One clue is to look at the single tiny LED right next to the control cable connectors; if it's lit green, then the Microplex signal is detected, if it's lit red the DMX signal is detected, if it's not lit at all (off) then no signal is detected which just may be an interface circuit failure. Such problems are a bit more challenging to troubleshoot internally, and requires a proper oscilloscope or logic analyzer.
In both of the above cases, you will see what may look normal on the LED display, but the dimmer pack will not function properly.
You should describe more symptoms of your problem, such as: Are all light output channels not working, or just 1 or 2? Which control interface are your using (Microplex or DMX)? What is your LED display saying? What are the present settings programmed into your D4DMX? Are any other working channels responding to the control console normally? What is the total length your control cables, including those between serial connected ("daisy-chained") multiple D4DMX dimmer packs? Do you have any non-D4DMX dimmers in the control chain, and are they all connected using the same type of control interface (Microplex or DMX)?

Just got a Chauvet Trident and plugged it in and the moter tunrs left then right , then stops ? The LED's blink 1 time then that is it ?


The left right motion is when the motor calibrates its position. The unit is then waiting for input... try generating a loud noise... if the audio gain is up and it is configured for manual rather than DMX it should start.
